Description
Technical field
The utility model belongs to Wind Power Utilization technical field, relates to a kind of high-altitude electricity generating device, specifically relates to a kind of kite generator.
Background technique
The petroleum-based energy of the world today, Coal Energy Source, natural gas energy resource are more and more deficienter, the fuel such as the coal that exploitation and without stint consumption are a large amount of and oil, bring serious negative effect, as bring out greenhouse effect, acid rain, cause the serious problems such as disease, the agriculture underproduction, greatly polluted the environment that the mankind depend on for existence, in addition war all over the world, natural disaster bring increasing difficulty, energy security to become one important problem of pendulum in face of the people of other countries to collection, the transportation of these energy.The problems that traditional energy faces provide objective reality demand, for example wind energy resources to emerging energy industry.
High altitude wind energy is the new energy that the mankind there is no exploitation so far, and this is abundant, the widely distributed renewable and clean energy resources of a kind of reserves.There is research to point out: high wind energy of containing always needs more than 100 times of the energy over human society in the air.Wherein, cube being directly proportional of the wind energy in high-altitude and wind speed, in general wind speed increases by 1 times, and wind energy increases by 8 times, so the several times of high altitude wind energy on can be above ground level, decades of times and even hundreds and thousands of times.Under high empty position reaches comparatively ideal situation, the theoretical generating dutation of high-altitude wind-powered electricity generation can surpass 95% of the annual time, and a year generating dutation can be up to more than 8200 hours.And conventional power generation usage reaches 2500 hours at the most. therefore, gather the wind-powered electricity generation that high altitude wind energy generating can obtain high stability, low cost of electricity-generating, this is one of distinguishing feature of high-altitude wind-powered electricity generation, is also that high-altitude wind-powered electricity generation is compared one of significant advantage of conventional wind-powered electricity generation, is also the development trend of following wind-power electricity generation.
So far, kite power generation mainly contains following several mode: the one, and make large-scale kite and carry propeller cavitation, generator and rise up into high-altitude and use power delivery that cable produces generator to ground.In this method, kite need to pull the equipment such as a large amount of cables and generator, propeller cavitation, thereby has the defect that heavy burden is large, lift-off is highly limited, energy conversion efficiency is low, and power generating equipment is unfavorable in high-altitude safeguarding; The 2nd, generator is placed in to ground, the cable driving by reciprocating kite drives the rotor of generator to generate electricity then, and winch is installed for reclaim cable when kite declines on ground, but this method can only produce electric energy at kite ascent stage, reclaims kite also will consume self energy by winch.Therefore, wind energy utilization is lower; In addition; foreign study personnel also propose to utilize the many groups of kites that are connected on support to pull ground disk to rotate; by electrical hoist, control kite bracing wire; realize aerial kite power generation; but this mode complex structure, process costs are high, and organize kite more and let together and be not easy to control easy generation wrapping phenomena fly away; Because kite is placed in height in the air by traction cable, the more windage that must cause of cable is larger, and generating exists intermittent, and generating efficiency is not high yet.
For example, U.S.'s patent of invention that the patent No. is US05544617 discloses a kind of windmill of automatic assembling, and windmill is put in the air and by wind energy, realizes windmill and at height, do reciprocal sporting flying in the air and realize generating.The shortcoming and the technical bottleneck that in the technological scheme of Fig. 5 in the disclosure of this patent of invention and Fig. 5 a, exist are: windmill or sail can only be done by cable reciprocal sporting flying and realize generating efficiently in low latitude.If windmill or sail are put into high when aerial, because circulation cable is very large in the aerial windage producing of height, so generating efficiency is not high.In addition, because the variation of flight path aloft of windmill, kite or sail causes the circulation cable generation line of pulley and pulley room poor, the generating efficiency of the terrestrial power generation device that exerts an influence that line is poor.
